Comparison of Error Protection Methods for Audio-Video Broadcast over DVB-H
EURASIP Journal on Advances in Signal Processing, 2007 The paper discusses methods for robust audio-video broadcast over the digital video broadcasting-handheld (DVB-H) system. DVB-H includes a link-layer forward error correction (FEC) scheme known as multiprotocol encapsulation (MPE) FEC, which provides ...

A Temporal-oriented Broadcast ResNet for COVID-19 Detection [PDF]
arXiv, 2022 Detecting COVID-19 from audio signals, such as breathing and coughing, can be used as a fast and efficient pre-testing method to reduce the virus transmission. Due to the promising results of deep learning networks in modelling time sequences, and since applications to rapidly identify COVID in-the-wild should require low computational effort, we ...

Orthogonal Frequency Division Multiplexing and its Applications [PDF]
nternational Journal of Science and Research (IJSR) Online ISSN:
2319-7064 , January 2013, 2013 Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation technique which is very much popular in new wireless networks of IEEE standard, digital television, audio broadcasting and 4G mobile communications. The main benefit of OFDM over single-carrier schemes is its ability to cope with severe channel conditions without complex ...
